There is a taper in the Facebook group that has tested this out using a Behringer UCA-202 interface ($30 on Amazon). I'm likely to give it a try for streaming or videos on my phone at some point.

yea, why not, right?   I might even build a rig around this.

I've recorded using a Foscusrite 2i2 connected via OTG cable to an android tablet.  Yes, it's technically possible.  What DAW are you going to use for editing?  Reaper, for example, is still either windows or mac.  The 2i2 and tablet combination is huge compared to a Sony M10. 

The more interesting question is what kind of results you could get using an android smartphone as a recorder with a decent mic.  Some of the smartphones like the Galaxy 7 are supposed to have amazing video quality.  If you could pair that with terrific audio recording quality, then that would be something.

i've got an LG V20 and the audio *playback* is quite good.  Better than my Galaxy 7 that I upgraded from by a long shot.  I would think it's good.....

So if I go Mixpre-6 mini output > UCA202 RCA input > UCA202 USB output > USB OTG Cable > Android USB + driver then I can broadcast my pull live via Mixlr? 

The problem is going to be how to keep my Android device charged if I have the USB input occupied.  Mixlr pulls my battery down pretty fast but perhaps it is just because I have accidentally had the recording button ticked.

You can get an OTG cable that provides power as well as the USB connection.

It looks like this driver only works with the developers apps, so it wouldn't help to get the audio into streaming software like mixlr. Correct me if I'm wrong, which I hope I am.

According to a taper on Facebook, as long as you start the app, other audio apps will also use it. He has a YouTube video about it.

Any update on whether anyone has tried this?  A link to the YouTube clip would rock

This doesnt work for me using Mixlr.

I bought the following:

Behringer U-Control UCA202: https://www.amazon.com/gp/product/B000KW2YEI/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
OTG cable: https://www.amazon.com/gp/product/B00V81L9M8/ref=oh_aui_detailpage_o00_s01?ie=UTF8&psc=1
eXtream USB Audio Recorder Pro (which apparently costs ~$6.50): https://play.google.com/store/apps/details?id=com.extreamsd.usbaudiorecorderpro&hl=en

I installed the app, I plugged UCA202 into the OTG and the OTG into my S8.  The interface powers fine.

I started USB ARP and it recognizes and initializes the USB audio device. 

I left the app open and started Mixlr and there is NO signal at all from the headphone out of my Mixpre-6 into Mixlr.  I used the headphone monitor on the UCA202 to confirm audio passing.  I can also record in USB ARP and it records fine.  I just cannot broadcast it using the Mixlr app.  Wit hthe OTG cable I cannot broadcast using the phone mics or from the OTG USB audio input.  If I remove the OTG cable from the phone then Mixlr uses the phone mics just fine. 

At this moment I have about $50 into something that doesn't look like it will work.  I don't mind trying with another platform if someone has another idea besides Facebook.  I wont use Facebook.

Are there any DAC's that work with this rig, but multi-track? Like 4-8 track inputs as opposed to stereo?

Does anyone NOT wanting to use Mixlr want to try this set up?  I'll send the OTG and UCA202 gear out and if it works then buy it and if it doesn't just send it back.  You will have the get the app on your own. 

This guys video shows it works with Facebook live so it may work with some other apps too.  I just needed it to work with Mixlr and it would not play nice.

A pm is fine.

I did a while ago a "backup recorder" using a behringer usb interface. works great (just "slide" the phone in, so it's very secure and "firm")

using extreamsd recorder, but others works too. (i like cause it records in FLAC).

now that i realized i can use it as a RTA analyzer ;)

tried with gaussian white noise (generated from Izotope Editor and played back from a DR-70D out) and the result is dead flat on the RTA.

so, the ADC/filtering on the behringer interface is very "neutral"

i can confirm that this driver does not work with ustream as well as mixlr. have not tried facebook live, but am a bit disappointed with my findings. i am rooted as well and checked the root box in the app settings hoping it might work but to no avail. if someone figures a workaround or other working solution with mixlr or ustream please report here

i tested mixlr on my moto x 2014, worked fine with my behringer usb interface.

android 6.0 rooted and very modded, as usual.

custom rom/kernel or stock? does it work without first running this driver/recording app (since stock 5.0+ has usb audio built in to a certain level)? do you have the root option checked in the recording app?

stock. rebooted the phone. just opened the mixlr program. worked without opening anything before (but i do have usb audio recorder from extreamsd)

i did not find any root option in the app. but my phone is rooted set to allow everything automatically.

I have an old Note 4 that I could root.  I am wondering if I should buy the behringer usb interface and try again with a rooted device. 

malow which behringer usb interface are you using?
Title: Re: USB audio driver / recording app for ANDROID
Post by: malow on February 19, 2018, 10:59:40 AM
behringer uca222
It uses a TI PCM2902 (I believe all models use some variation of TI chips)
Title: Re: USB audio driver / recording app for ANDROID
Post by: binone on April 01, 2019, 08:18:32 AM
Any improvement on this?

does the 222 works with mixlr?

Is the recorder soft needed for use with mixlr?


Thanks

is this asynchronous?

i was talking with doug about the d:vice and while he was impressed with the internals, said most usb connections like that are synchronous and very prone to jitter

i have a digigram uax-220 mic (listed as supported) that would be good to test with this. as with all things digigram the breakout cables are obscene
